.Afofthe opoeeifneeodoef @bei eekiffem is rigidly attached an upwardly projecting bracket 23 having a socket 24 into which is fixed the upper end of an inclined shaft 25. Upon the lower end of the shaft 25 is formed a head 26 having an eye which engages the coupling bolt 16, and this head is also provided with a shoulder to engage the hardened and polished steel plate 27 fitted into the lower end of the inclined pulley 28. The pulley 28 is of similar construction with the pulley 19 and is provided at each end with a plurality of longitudinally extending rollers 29 which engage the inclined shaft 25 to form antifriction bearings for the support of the pulley 28. The upper end of the pulley 28 is closed by a suitable flange 30 formed on the socket 24 which lits sufficiently close to exclude dirt from the inside of the pulley without occasioning frictional resistance to its rotation.

Formed in the jack frame 7 near the end opposite the operator is a longitudinally extending slot 31 in which is slidably mounted a slide block 32. Formed on the slide block 32 are 1 upwardly projecting lugs 33 through which extends the pivot bolt 34. Freely mounted upon the pivot bolt 34 are two links 35 which also engage a coupling bolt 36 attached to the head 37 of a shaft similar to the shaft 25, upon which is mounted 'a pulley 38 of similar construction to the pulley 28. At its lower end this shaft is provided with a head 39 which pivotally engages the coupling bolt 16. Attached to the slide block 32 is a pull rod 40 extending longitudinally of the jack frame and provided with a handle 41 convenient to the hand of the operator.

When one of the idler pulleys which support the belt 2 has become deranged, my

improved lifting jack may be inserted beneath the belt adjacent the defective idler pulley, and the clamping members 4 adjusted to securely hold the main frame 1 in operative relation to the belt. By pulling the pull rod 40 towards him the operator will cause the pulley 38 to assume the inclined position shown by dotted lines in Fig. 1. The operator then rotates the hand wheel 14 to elevate the jack frame 7 to cause the pulleys 19, 28, and 38 to engage the conveyer belt 2 and lift it clear of the defective idler pulley. The conveyer belt 2 may thus continue in operation during the repair of the defective parts, after which the hand wheel 14 may be rotated to lower the pulleys 19, 28, land 38 away from contact with the conveyer belt. The rod 40` may be pushed from the operator to restore the pulley 38 to its horizontal position, the clamping members 4 loosened and the entire apparatus withdrawn, to be available for use at another time and place.

From the foregoing it will be seen that the movable pulleys 38 when aligned with the pulleys 1.9 as shown in Figure 1, permit to be removably secured in position beneath a conveyer belt, an auxiliary frame adjustably connected with said main frame, a plurality of idler pulleys mounted uponV said auxiliary frame, and means to vertically adjust said auxiliary frame relative toy said main frame as and for the purpose set forth. Y 2. In an apparatus ofthe classdescribed, the combination with a main frame adapted to be removably secured in position beneath a conveyer belt, an auxiliary frame adjustably connected with said main frame, a plurality of idler pulleys mounted upon said auxiliary frame, means to adjust some of said pulleys to conform to the contour of said conveyerV belt, and means to vertically adjust said auxiliary frame relative to said main frame as and for the purpose set fort-h.

3. In an apparatus of the class described, the combination with a main frame adapted to be removably secured in position beneath a conveyer belt, an auxiliary frame adjustably connected with said main frame, a plurality of idler pulleys mounted upon said auxiliary frame, manually controllable devices to adjust some of said pulleys to conform to the contour of said conveyer belt, and manually controllable means to vertically adjust said auxiliary frame relative to said main frame as and for the purpose set forth. e Y

4. In an apparatus of the class described, the combination of a main frame adapted to be removably mounted beneath a conveyer belt, an auxiliary frame adjustably Vconnected with said main frame, a plurality of flexibly connected idler pulleys mounted upon said main frame with the ends of some of said pulleys unobstructed,means for raising or lowering some of said Vpulleys to inclined or aligned positions relative to others of said pulleys, and means for 'adjusting said auxiliary frame vertically. j

5. In an apparatus of the class described the combination of a main frame )adapted to be removably mounted beneath al conveyer belt, an auxiliary frame adjustably connected with said main frame, 'a plurality of flexibly connected idler pulleys mounted upon said main frame with the ends of some of said pulleys unobstructed, means for raising` or lowering pulleys on one side of said frame .to inclined or aligned positions relative to others of said pulleys, and means for adjusting said auxiliary frame vertically.

6. In an apparatus of the class described,

the combination of a main frame adapted l to be removably mounted beneath a conveyei' belt, an auxiliary frame adjustably connected with said main frame, a plurality of flexibly connected idler pulleys mounted upon said main frame to lie transversely of l. a conveyer with the ends of some of said pulleys unobstructed, slide blocks connected tion relative to others of said pulleys, and l means operable from the same side of the fra-me as the `slide block operating means to adjust said auxiliary frame vertically.

In testimony whereof, I alix my signal0v ture.
